When, How and Why?

The When, How and Why about our very existence. This is how I would grade the two general schools of thought:

Theists Atheists/ScienceWhen Wrong Evidence and Much DiscoveryHow Wrong Evidence and Much DiscoveryWhy God's Will No Explanation

Do you think science or atheism does, can and/or will ever answer Why? Must there even be a "reason" for the Universe.I do not think "to do good" is a necessarily a valid answer for atheists; why do good? It may be a valid answer for a theist. I feel the "why" questions undermines atheism because religion offers an (albeit, a ridiculous) answer. What are your thoughts on this matter?
